pid(n) Tcl Built-In Commands 7.0
_________________________________________________________________
NAME
pid - Retrieve process id(s)
SYNOPSIS
pid ?_f_i_l_e_I_d?
_________________________________________________________________
DESCRIPTION
If the _f_i_l_e_I_d argument is given then it should normally
refer to a process pipeline created with the open command.
In this case the pid command will return a list whose ele-
ments are the process identifiers of all the processes in
the pipeline, in order. The list will be empty if _f_i_l_e_I_d
refers to an open file that isn't a process pipeline. If no
_f_i_l_e_I_d argument is given then pid returns the process iden-
tifier of the current process. All process identifiers are
returned as decimal strings.
KEYWORDS
file, pipeline, process identifier
